Educational institutions increasingly face the challenge of accommodating learners from a wide range of linguistic and cultural backgrounds in their classrooms. The training kit presents an innovative way of managing diversity in the classroom by combining plurilingual and pluricultural approaches with content-based instruction. The reader will discover how content-based and plurilingual activities can be linked to several subjects of the curriculum.The accompanying website presents sample activities which illustrate the approach outlined in the rationale. A primary school teacher will, for example, find an activity suitable for mathematics, sports and/or music and a secondary school teacher of civic, social and political education may be interested in testing out plurilingual comparative text work on the theme of the Universal Declaration of Human Rights.WHAT IS ITS ADDED VALUE?The training kit:* assists teachers in creating content-based and plurilingual materials in English, French and Spanish that can be linked to several subjects of the curriculum;* promotes strong links between language teachers and teachers of other disciplines.
